Garbage carried by the wind across the field. Ecological pollution.

Contamination and waste

This dependency category covers direct and indirect reliance on an absence or relative infrequency of contamination of land and/or the presence of waste.

Metric:

Proportion of land area unaffected by contamination and waste

Units

Percentage (%)

Example target

Benchmark against best practice

Example methods / guidance / references

What are tiers?

Tier 1

Estimate using own judgement and observations

Tier 2

Estimate using third-party professional estimates or public data

Tier 3

Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.

Example data sources

Internal records

Third-party data sources

Notes

“Unaffected by’ means not subject to land/freshwater/ocean-use change during the reporting period, e.g. agricultural land remaining agricultural land. Note that land/freshwater/ocean-use change may be derived from Land accounts (see Environmental assets tab). For example, land conservation or restoration may involve a change from a more intensive use (e.g. class 1.1 Agriculture) to a less intensive use (e.g. class 1.5 Land used for maintenance and restoration of environmental functions, or class 1.7 Land not in use). Additional analysis may be required to determine the extent to which measured change has been caused by the reporting entity. Variants of this metric include TNFD core disclosure metric C1.1: “Extent of land/freshwater/ocean ecosystem use change (km2) by:
• Type of ecosystem; and
• Type of business activity.
Extent of land/freshwater/ocean ecosystem conserved or restored (km2), split into:
• Voluntary; and
• Required by statutes or regulations.
Extent of land/freshwater/ocean ecosystem that is sustainably managed (km2) by:
• Type of ecosystem; and
• Type of business activity.”
and additional disclosure metric A1.0: “Land-use intensity (tonnes or litres of output/km2). This will vary by sector context; for example, crop yield (tonnes/km2) for the agriculture sector.”
